“…Soil nutrient cycling processes (e.g., nitrogen cycling) are also responsible for the re-distribution of primary P i into P o forms over timescales of 10 4 -10 6 years [30]. The widespread application of P o -containing products, such as plasticizers, fire retardants, antifoam agents, and pesticides, has resulted in their frequent occurrence in the environment as new P o sources, consequently increasing the quantities and varieties of P o forms in soils [31][32][33]. into Po forms over timescales of 10 4 -10 6 years [30].…”

The widespread application of Po-containing products, such as plasticizers, fire retardants, antifoam agents, and pesticides, has resulted in their frequent occurrence in the environment as new Po sources, consequently increasing the quantities and varieties of Po forms in soils [31][32][33]. Unlike Po, which is more easily leached because of weak interactions with the soil particles [34], soil Pi is usually present as relatively insoluble and stable forms of primary (including apatite, strengite, and variscite) and secondary (including calcium, iron, and aluminum phosphates) P minerals [35][36][37][38].…”

“…Soil P o , which derives mainly from biomolecules, including nucleotides, phosphides, co-enzymes, phosphoproteins, sugar phosphates, and phosphonates, plays an essential role in soil P cycling [2][3][4]. P o substances (e.g., orthophosphate esters, phosphonates, and polyphosphates) are mostly short-lived compounds, and may comprise as much as 65% of P t in most soils [31,44]. Based on its sources, soil P o can be considered to exist in a rapidly cycling pool (fast P o ) and a slowly cycling pool (slow P o ) [44].…”

Phosphorus (P) is a vital element in biological molecules, and one of the main limiting elements for biomass production as plant-available P represents only a small fraction of total soil P. Increasing global food demand and modern agricultural consumption of P fertilizers could lead to excessive inputs of inorganic P in intensively managed croplands, consequently rising P losses and ongoing eutrophication of surface waters. Despite phosphate solubilizing microorganisms (PSMs) are widely accepted as eco-friendly P fertilizers for increasing agricultural productivity, a comprehensive and deeper understanding of the role of PSMs in P geochemical processes for managing P deficiency has received inadequate attention. In this review, we summarize the basic P forms and their geochemical and biological cycles in soil systems, how PSMs mediate soil P biogeochemical cycles, and the metabolic and enzymatic mechanisms behind these processes. We also highlight the important roles of PSMs in the biogeochemical P cycle and provide perspectives on several environmental issues to prioritize in future PSM applications.

“…Both of these concepts are well demonstrated by heavy metals (described in detail in the following paragraph), which can be deposited on roadways through metal corrosion, braking, tire wear, and exhaust. The latter of these two concepts (infiltration of phosphate in soil near the roadside) have been demonstrated in the recent works of Fabiańska et al (2019) and Cui et al (2017). These studies reported highly variable concentrations of organophosphate in roadside soil samples, indicating that the distribution of phosphorous in roadside soils is dependent on soil properties, traffic volume, and vehicle idling.…”

It is well documented that urban runoff and roadside soils can become contaminated with particulate deposits, especially heavy metals, sourced from vehicles. However, phosphorous from vehicular sources has been given little consideration as a possible roadside contaminant. This paper examines the potential contamination of surface water (via runoff to storm drains and discharge to waterbodies) and groundwater (via roadside soil infiltration) by the phosphorous deposited onto pavement and road shoulders in the city of Waterloo, Ontario, Canada. Total and soluble reactive phosphorous concentrations in roadside soil and runoff samples were determined for two study sites. Subsequently, the results were statistically analyzed. Following comparison to other sources of urban runoff, it was concluded that roadways are a significant source of phosphorous in urban runoff, with high potential to impact surface water. Conversely, results of this work indicate that vehicular-sourced phosphorous does not pose a significant threat to groundwater.

“…Chlorinated OPEs are routinely detected in effluent, indicating difficulty removing them during the treatment process, while some alkylated OPEs like TBOEP, show an affinity to sludge (Lettieri et al, 2013;Quintana et al, 2008b;Tang et al, 2019). Primary sources for OPEs entering WWTPs may include road run-off and laundry wastewater as a result of household dust accumulating on textiles and transferring to laundry water (Fabiańska et al, 2019;Saini et al, 2016;Schreder & La Guardia, 2014).…”

Metabolism and fate of organophosphate ester (OPE) contaminants in rainbow trout (Oncorhynchus mykiss) using in vitro lab-based studies

Due to ubiquitous use of organophosphate esters (OPEs) as flame retardants and plasticizers, they have been found at high concentrations in a variety of environmental media while having low or non-detectable levels in biota, including fish. The exposure and fate of OPEs in fish depends on understanding the toxicokinetics, though studies on OPE metabolism are lacking. A model in vitro microsomal-based metabolism assay for rainbow trout (Oncorhynchus mykiss) was utilized to investigate OPE metabolism. Metabolic depletion was only noted for 2 alkyl OPEs and formation of corresponding diester metabolites was low, indicating other unidentified metabolites were formed. Comparison with avian and mammalian models showed fish generally had slower and less complete metabolism, illustrating species-specific differences in biotransformation. Structure also influenced OPE metabolism in that bulky, aryl OPEs were not metabolized. These results provide important information of toxicokinetic processes that can affect the exposure and fate of OPEs in rainbow trout. Chapter 1: General Introduction 1.1 Flame Retardant Chemicals and Organophosphate Esters In today's homes and public spaces, flammability concerns are well warranted. Increased use of plastics, foams, synthetic fiber-base fillings, and electronics bring an increased risk of fire as many of these polymers can be highly flammable. Industry flammability standards, such as California's Technical Bulletin 117, were implemented in an effort to reduce fires and increase average escape time (US EPA, 2007) and, as a result, production and use of flame retardants has become common practice to meet flammability standards in various consumer goods, textiles, furniture, electronics, and plastics.
